SHA FT-HANG ER.

SPECIFICATION forming part of Letters Patent No. 743,619, dated November10, 1903.

Application filed September 26, 1902. Se i l N 124.981. (No model.)

To all whom it may concern:

Be it known that I, EMLEN V. CREssoN, of Philadelphia, in the countyofPhiladelphia,

and in the State of Pennsylvania, have invents.

ed a certain new and useful Improvement in Shaft-Hangers; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which- Figure l is a perspective view of a shafthanger embodying myinvention. Fig. 2 is an end elevation, partlyin section. Fig. 3 is ahorizontal section on the line 3 3 of Fig. 2; and Fig. 4 is a detailview in perspective of the head of the hanger, the two parts thereofbeing shown as separated from each other. I

The object of my invention is the production of a shaft-hanger havingthe qualities of all adaptability that is requisite in view of thevarious drops and sizes of shafts for which it may be used, so as toreduce to a minimum the number of hangers required to bekept in stock,of convenience in mounting and dismounting the shaft, and of possibilityof cheap manufacture; and to these ends my invention consists in theshaft-hanger having the construction substantially as hereinafterspecified and claimed.

In the embodiment of my invention which is illustrated in the drawingsthere is employed a cast base or frame A, comprising two upright and twohorizontal members, one of the horizontal members being at the upper endof the two vertical members and two elongated holes or slots a beingformed therein for the passage of bolts for the attachment of i thehanger to a beam or rafter and the other horizontal member being at apoint substantially midway between the ends of the upright members, thelower part of the frame or'base being thus open at one end or in theform of a fork. Of course the form and design of the frame made can bevaried as desired, it being necessary only thatits lower end he forkedor open. Secured to the base or frame A by two bolts B, thatrespectively pass through the vertical slots a in the lower portions ofthe upright members of the frame or base, is an open frame 0, having thegeneral form of a rectangle, thesaid frame having on opposite sides lugsor projections c, that have horizontal slots 0, through which thefastening-bolts B pass. The slots 0 are located at a point to one sideof a point half-way from top to bottom of the frame 0, for a reasonhereinafter given. Upon one side of the lugs o of the frame 0 there areheavy horizontal ribs 0 that engage similar ribs 0. on the side of thebase or frame A, the said ribs thus supplementing the bolts as means forsupporting the frame 0. Upon the opposite side of each.

of the lugs a disk D is pivoted eccentrically upon the bolt B, whichgoes through such lug and engages by its periphery a projection c on thelug. By the revolution of the eccentric disk it may be placed in contactwith the projection c whatever be the position to which the head may beshifted horizontally, and as there are two disks, with a projectionforeach, the head will thereby be firmly held from lateral movement ineither direction.

Within the frame O or head, as I shall term it, is supported the shaftbox or bearing E, the construction of which need'not be described, as ithas nothing to do with this invention, Said box or hearing is engagedabove and below by screws F, the head 0 being perforated for each screwand having a cavity to accommodate an internally-threaded block or notfor the screw. As is usual, each screw is provided withalock-nut f. Infixing the position of the box or bearing vertically thehead C is movedvertically to the desired position as near as the ribs will per unit,and then by means of the screws F such further adjustment as may benecessary is effected. It will be observed that the screws F are carriedby the parts having the ribs,

which parts form elements of the means for be unnecessary in mounting ordismounting the shaft to move the shaft endwise through the hanger, andto meet this requirement the head 0 is made in halves, the joint extending Vertically through the lugs c and opening out at opposite ends onopposite sides of the head,there being thus overlapping portions of thehangers where the lugs c are. The bolts B, which secure the head to thebase or frame A, thus serve to bind the halves of the head together,although, as a matter of convenience, to enable the head to be appliedto the shaft While the latter is on the floor before being raised to thehanger, bolts G, such as stovebolts, are employed to join the halves.The adjoining ends of the portions of the halves or sections of the head0 that overlap are given such form as to resist lateral or sidewisetendency of the halves or sections relative to each other, and this formis preferably that of inclined surfaces, the inclination on both sidesof the head being downward and inward in the case of those surfacesabove a horizontal plane passing through the slots 0 and upward andinward in the case of the surfaces on the opposite side of such plane.The sides of the box or bearing E abut or bear directly against theinner sides of the head 0, so that said box or bearing is most firmlyand substantially supported. The sides of the head against which the boxor bearing abut are slightly curved, and as the surfaces of the boxwhich engage them are flat it will be evident that the box can rocklaterally as may be required by the shaft. The bearing-points of thebolts F and the box permit such lateral movement and also such rockingup-anddown movement of the box, as may be required. I 7

It will be seen that from the divided or sectional form of the head 0the shaft does not have to be moved endwise in mounting or dismounting,but when, for example, it is to be mounted the head can be applied to itwhileit is on the floor; that by reason of the vertical slots at in thebase or frame A and also by reason of the invertibility of the head 0,due to the eccentric location of the slots 0, a wide range of verticaladjustmentisprovided,a feature that makes it possible to largely reducethe number of varieties of hangers to be carried in stock; that byreason of the ribs a and c and the horizontal position of the bolts Bthe head has a most substantial support, being in this respect greatlysuperior to a construction where vertical bolts are employed, so thatthe weight has to be sustained only by the threads of the bolts; thatbesides vertical adjustment the horizontal slots 0' permit horizontaladjustment; that by reason of the completeness of the head and its modeof attachment to the base or frame A it is interchangeable with bases orframes of different heights, one head being thus adapted for use with anumber of bases or frames, a thing of considerable importance where, forexample, the position of shafting in a mill is to be shifted and the newlocation requires a base or frame of different drop from that of theold, it thus being necessary not to discard all of the old hangers, butsimply to discard the old bases or frames, and that the head 0 permitsthe employment of different bearings or boxes, so that self-oiling orplain boxes may be used and so that boxes for shafts of various sizesmay be used. The sectional form of the head is also a valuable feature,since it enables packing in smaller space than would otherwise bepossible, a consideration that is of importance in shipment where thecharge for transportation is based upon the space occupied and not onweight. Besides the advantages mentioned my hanger is very cheap tomanufacture, since the parts are easily cast, all of the horizontalholes being self-coring, while the cheapest cores are required for thevertical holes, of which there are but four.

I of course do not limit the scope of my invention to the details ofconstruction shown and described, as changes in many particulars can bemade which will involve no departure from the spirit of myinvention. Forexample, instead of the holes a and a being elongated or in the form ofslots they can be round or square.
